All Flashcards
How do diatonic sequences reinforce the tonic key?
By emphasizing notes within the tonic key, creating stability.
How do chromatic sequences create tension?
By introducing notes outside of the current key.
What is the typical function of a sequence moving by step?
Can prolong the tonic or modulate to closely related key.
What is the typical function of a sequence moving by third?
Can prolong the tonic or modulate to a more distant key.
What is the typical function of a sequence moving along the circle of fifths?
Often used for strong modulations to new keys.
What is a melodic sequence?
A musical pattern repeated at different pitch levels.
What is a pattern in a melodic sequence?
The original musical idea that is repeated.
Define 'level of transposition'.
The interval by which each repetition of the pattern is shifted.
What is a diatonic sequence?
A sequence that stays within the key.
What is a chromatic sequence?
A sequence that uses accidentals to maintain interval quality or modulate.
What is an ascending sequence?
A sequence where the pattern moves upward in pitch.
What is a descending sequence?
A sequence where the pattern moves downward in pitch.
What is the main function of melodic sequences?
To develop musical ideas and create continuity and change.
What is the role of diatonic sequences in establishing a key?
They reinforce the tonic key by emphasizing notes within it.
How do chromatic sequences lead to modulation?
By introducing notes outside of the current key, creating tension and motion.
How do sequences prolong the tonic area?
By repeating patterns that emphasize notes within the tonic key, creating stability.
How do sequences signal motion to a new key?
By gradually introducing notes from the target key, often using chromatic alterations.
What is the function of a diatonic sequence?
To establish and reinforce the tonic key.
What is the function of a chromatic sequence?
To create tension, forward motion, and modulation.
